Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a sorting device and a sorting method for finished infusion bags in a medical intravenous admixture station. Background Art

[0002] As a basic infusion supply, intravenous infusion bags are extremely widely used. After the infusion is prepared, it is necessary to match the infusion bags with specific patients and classify and pack them according to the ward area, so that medical staff can timely send the infusion bags to the ward area for patient treatment. In this process, the sorting of infusion bags is a key step, and the main methods include manual sorting and mechanical sorting. Manual sorting has gradually been replaced by mechanical sorting due to its low efficiency, high labor intensity, and high error rate. Modern hospitals generally adopt mechanical sorting systems to improve the efficiency and accuracy of infusion bag sorting.

[0003] The mechanical sorting process is usually realized by special sorting equipment, which mainly consists of the following core components: a control system, a sorting mechanism, a conveying system, and sorting outlets and infusion boxes. The function of the sorting mechanism is to respond to the instructions issued by the control system. When the conveying system moves the infusion bag to a predetermined sorting position, the sorting mechanism will guide the infusion bag to the corresponding sorting outlet and make it slide into the infusion container. In current sorting equipment, most adopt a push-type driving mechanism to push the movement of the infusion bag. This mechanism uses a push plate to push the infusion bag along a predetermined path to the correct sorting position. For example, Chinese invention patent CN105035730B discloses a sorting machine for multi-station infusion bags, and specifically discloses including: a machine body, on both sides of which are symmetrically provided with a plurality of sorting cavities, and accommodation boxes are arranged in the sorting cavities; an upper conveyor belt and a lower conveyor belt, which are arranged side by side up and down in the machine body, and a plurality of support plates are equally spaced on both sides; at least two dial units, which are all supported by the support plates, and the dial units are respectively arranged corresponding to the accommodation boxes on both sides. The sorting machine for multi-station infusion bags provided by the present invention can intelligently control the entire working process by connecting the first sensor, the second sensor, the scanner with the controller and the touch display screen; by setting the rotating plate unit, the safely conveying and effectively protecting the conveyed infusion bags can be achieved; by cooperatively setting the positioning plate and the limiting plate, the tension adjustment of the dial unit can be carried out; by arranging the dial and the folding plate at a certain angle.

[0004] Although the mechanical sorting system can effectively complete the sorting task of infusion bags, due to the differences in the types and doses of drugs in the infusion bags, the materials, surface smoothness, and internal drug capacities of the infusion bags are all different. These factors cause problems such as bag jamming when conveying infusion bags with different characteristics, especially infusion bags with a matte texture on the surface, less liquid medicine, and infusion bags containing soft components such as rubber stoppers, thus affecting the sorting efficiency.

[0005] Therefore, it is very necessary to study a sorting device and sorting method for finished infusion bags in a medical intravenous admixture station that can be applied to various types of infusion bags. Summary of the Invention

[0043] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence.

[0044] Embodiment 1

[0045] Please refer to Figures 1 to 11 As shown, a sorting device and sorting method for finished infusion bags in a medical intravenous configuration station include: a frame 1 for supporting, dust-proofing and inputting information for medical staff, a sorting mechanism 2 for sorting infusion bags to designated positions, and a positioning mechanism 3 for adjusting the positions of the infusion bags on the sorting mechanism 2.

[0046] A feeding conveyor belt 11, a ring conveyor 12, an infusion box 13 and a control device 14 are arranged on the frame 1. The feeding conveyor belt 11 and the control device 14 are fixedly installed at the entrance of the frame 1. It can be understood that medical staff can input information through the control device 14, and then place the prepared infusion bags on the feeding conveyor belt 11. The feeding conveyor belt 11 conveys the infusion bags to the sorting mechanism 2 of the ring conveyor 12. The infusion box 13 is slidably arranged at the exit of the frame 1. The ring conveyor 12 is installed inside the frame 1. That is, after the position is adjusted by the positioning mechanism 3, the sorting mechanism 2 moves the infusion bags to the corresponding infusion box 13, and then the sorting mechanism 2 drags the infusion bags to the infusion box 13.

[0047] The sorting mechanism 2 includes a sorting bracket 21, a suction cup assembly 22, a magnet assembly 23 and a driving bracket 24.

[0048] The sorting bracket 21 is installed on the ring conveyor 12. A suction cup groove 211, a rectangular groove 212, a sensor 213 and a guide sleeve 214 are arranged on the sorting bracket 21. The suction cup groove 211 is arranged above the sorting bracket 21. The rectangular groove 212 is arranged on one side of the sorting bracket 21 close to the infusion box 13. The sensor 213 is arranged on the side far from the rectangular groove 212. The guide sleeve 214 is arranged below the sorting bracket 21. It can be understood that the sensor 213 can detect the position of the infusion port on the infusion bag.

[0049] The suction cup assembly 22 includes a suction cup 221, a turntable 222, a metal disc 224, and a first spring 225. The suction cup 221 is disposed on the turntable 222, that is, the suction cup 221 can cooperate with the infusion bag and fix it on the sorting mechanism 2 by adsorbing the infusion bag so that it cannot move or rotate. The turntable 222 is rotatably disposed in the suction cup groove 211. The turntable 222 is connected to the frame 1 through the first spring 225. The metal disc 224 is disposed below the turntable 222, and the metal disc 224 can be attracted by the magnet 231 of the magnet assembly 23. It can be understood that when the suction cup assembly 22 is in the released state: at this time, there is no external force acting, the first spring 225 releases its elastic force and elongates, so that the turntable 222 and the suction cup groove 211 just do not contact, and at this time, the turntable 222 can freely rotate in the suction cup groove 211; when the suction cup assembly 22 is in the locked state: when the suction cup assembly 22 is forced to slide downward along the suction cup groove 211 as a whole, the first spring 225 is compressed under force, and the turntable 222 and the suction cup groove 211 are in extrusion fit. Preferably, a rubber pad 223 is further disposed at the bottom of the turntable 222, and the rubber pad 223 is in extrusion fit with the suction cup groove 211 to restrict the rotation of the turntable 222 through friction.

[0050] The magnet assembly 23 includes a magnet 231, a second guide rod 232, and a second spring 234. The magnet 231 is fixedly disposed above the second guide rod 232. The second guide rod 232 is slidably disposed in the guide sleeve 214. The second guide rod 232 is connected to the bottom of the guide sleeve 214 through the second spring 234. It can be understood that the second spring 234 can push at least a part of the second guide rod 232 out of the guide sleeve 214, so that the magnet 231 moves upward and approaches the metal disc 224. When the distance between the two is reduced to a certain extent, the magnet 231 attracts the metal disc 224 to move downward, and then drives the suction cup assembly 22 to slide downward as a whole, so that the suction cup assembly 22 changes from the released state to the locked state. Specifically, a first push rod 235 and a second push rod 236 are further disposed on the magnet assembly 23. The first push rod 235 and the second push rod 236 are fixedly disposed on the second guide rod 232, that is, pushing the first push rod 235 or the second push rod 236 downward can make at least a part of the second guide rod 232 slide into the guide sleeve 214, so that the metal disc 224 is separated from the adsorption of the magnet 231. Under the action of the first spring 225, the suction cup assembly 22 will switch from the locked state to the released state. Correspondingly, a positioning groove 215 is further disposed on the sorting bracket 21, and a positioning block 233 is further disposed on the second guide rod 232 of the magnet assembly 23. The positioning block 233 is slidably disposed in the positioning groove 215, that is, the positioning block 233 cooperates with the positioning groove 215 to prevent the magnet assembly 23 from rotating, thereby causing the positions of the first push rod 235 and the second push rod 236 to shift.

[0051] The driving bracket 24 includes a rack 241, a driving rod 242, a connecting rod 244, a slider 245, a first driving motor 246, a second driving motor 247, and a lifting hook 248. The rack 241 is slidably disposed on the sorting bracket 21. The first driving motor 246 is engaged with the rack 241. It can be understood that the first driving motor 246 can drive the rack 241 to slide along the sorting bracket 21. The driving rod 242 is rotatably connected to the rack 241. Correspondingly, the second push rod 236 is slidably engaged with the driving rod 242 and the connecting rod 244. Correspondingly, the connecting rod 244 is slidably engaged with the second push rod 236 and cannot push the second push rod 236 downward. When the driving rod 242 is engaged with the second push rod 236, it can push the second push rod 236 downward, thereby driving the magnet assembly 23 to slide downward along the guide sleeve 214. Correspondingly, a first guide rod 216 is further disposed on the sorting bracket 21, and a reversing groove 243 is further disposed on the driving rod 242 of the driving bracket 24. The first guide rod 216 is slidably engaged with the reversing groove 243. It can be understood that when the first driving motor 246 drives the rack 241 and the driving rod 242 to slide toward the infusion box 13, when the slider 245 moves above the infusion box 13, the first guide rod 216 and the reversing groove 243 cooperate to drive the driving rod 242 to flip downward by 90 degrees. The slider 245 is connected to the driving rod 242 through the connecting rod 244. The slider 245 is slidably disposed in the rectangular groove 212. The lifting hook 248 is slidably disposed on the slider 245. The second driving motor 247 is connected to the lifting hook 248. Specifically, teeth 249 are further disposed on the lifting hook 248. The second driving motor 247 is engaged with the teeth 249 through a gear. It can be understood that the second driving motor 247 can drive the lifting hook 248 to slide upward and extend out of the slider 245 through the gear and the teeth 249, and can drive the lifting hook 248 to slide downward and retract into the slider 245. After at least a part of the lifting hook 248 extends out of the slider 245, when the first driving motor 246 drives the slider 245 to move along the rectangular groove 212 toward the infusion box 13 through the rack 241, the driving rod 242, and the connecting rod 244, the lifting hook 248 is inserted into the hanging hole of the infusion bag.

[0052] The positioning mechanism 3 includes a lifting component 31 and a positioning component 32. The lifting component 31 is fixedly connected to the frame 1, and the positioning component 32 is installed on the lifting component 31. Specifically, the lifting component 31 includes a optical bar 311, a lead screw 312, a slide plate 313, a third driving motor 314, and a push rod 315. The optical bar 311 is fixedly arranged on the frame 1, the lead screw 312 is rotatably arranged on the frame 1, the rotating shaft of the third driving motor 314 is fixedly connected to the lead screw 312, the slide plate 313 is slidably arranged on the optical bar 311, the slide plate 313 is matched with the lead screw 312, and the push rod 315 is fixedly arranged on the lower end face of the slide plate 313. It can be understood that the third driving motor 314 drives the lead screw 312 to rotate, and then drives the slide plate 313 to slide up and down along the optical bar 311. Correspondingly, the first push rod 235 is in extrusion fit with the push rod 315. It can be understood that when the slide plate 313 slides down, the push rod 315 is in pressure fit with the first push rod 235, so as to push the magnet assembly 23 to slide down integrally through the first push rod 235, and switch the suction cup assembly 22 from the locked state to the released state.

[0053] Specifically, the positioning component 32 includes a positioning bracket 321, a third guide rod 322, a third spring 323, a slide rod 324, a spherical contact 325, an elastic contact 326, and a fourth driving motor 329. The fourth driving motor 329 is fixedly arranged on the slide plate 313, and the positioning bracket 321 is fixedly arranged on the rotating shaft of the fourth driving motor 329. It can be understood that the fourth driving motor 329 can drive the positioning component 32 to rotate below the slide plate 313. The third guide rod 322 is fixedly arranged, the slide rod 324 is slidably arranged on the positioning bracket 321, the third guide rod 322 is slidably matched with the slide rod 324, the slide rod 324 is connected to the positioning bracket 321 through the third spring 323, a spherical contact 325 is arranged at the lower end of the slide rod 324, and the elastic contact 326 is installed on the spherical contact 325. It can be understood that the lifting component 31 drives the positioning component 32 to move downward until part of the elastic contact 326 contacts the infusion bag. At this time, the slide rod 324 connected to this part of the elastic contact 326 slides upward along the third guide rod 322, so that the third spring 323 is compressed under force, and at this time, the elastic contact 326 is in extrusion fit with the infusion bag.

[0054] A middle hole 327 and an elastic connection cord 328 are provided on the elastic contact 326. The middle hole 327 is arranged at the lower end of the elastic contact 326, and the adjacent elastic contacts 326 are connected by the elastic connection cord 328. Correspondingly, the two electrodes forming the switch are respectively connected to the sliding rod 324 and the sorting bracket 21. This part is the prior art and will not be elaborated here. It can be understood that during the process of the lifting assembly 31 driving the positioning assembly 32 to move downward, the elastic contacts 326 that do not contact the infusion bag continue to descend until the elastic contacts 326 contact the sorting bracket 21. During this process, the spherical contact 325 passes through the middle hole 327 and contacts the sorting bracket 21. At this time, the travel switch is triggered and the lifting assembly 31 stops descending. The elastic connection cord 328 covers the infusion bag and is in extrusion fit with the infusion bag; the fourth driving motor 329 drives the positioning assembly 32 to rotate, and then the infusion bag and the suction cup assembly 22 can be driven to rotate on the sorting bracket 21 by the positioning assembly 32. When the sensor 213 detects the infusion port of the infusion bag, the fourth driving motor 329 stops rotating.

[0055] The working principle of the present invention is as follows:

[0056] After the medical staff prepare the infusion bag, the medical staff can input information through the control device 14, and then place the prepared infusion bag on the feeding conveyor belt 11.

[0057] The feeding conveyor belt 11 conveys the infusion bag to the sorting mechanism 2 of the ring conveyor 12; at this time, the suction cup assembly 22 is in the locked state, and the infusion bag is located above the upper suction cup 221 of the suction cup assembly 22; the ring conveyor 12 conveys the sorting mechanism 2 carrying the infusion bag to the lower part of the positioning assembly 32; the lifting assembly 31 drives the positioning assembly 32 to move downward until part of the elastic contact 326 contacts the infusion bag. At this time, the slide bar 324 connected to this part of the elastic contact 326 slides upward along the third guide rod 322, causing the third spring 323 to be compressed under force. At this time, the elastic contact 326 is in extrusion fit with the infusion bag, and the elastic contacts 326 that do not contact the infusion bag continue to descend until the elastic contact 326 contacts the sorting bracket 21. During this process, the spherical contact 325 passes through the middle hole 327 and contacts the sorting bracket 21. At this time, the travel switch is triggered, and the lifting assembly 31 stops descending. The elastic connecting rope 328 covers the infusion bag and is in extrusion fit with the infusion bag; at the same time, during the process of the positioning assembly 32 descending and being in extrusion fit with the infusion bag, the push rod 315 pushes the first push rod 235 downward, causing the magnet assembly 23 to slide downward. The magnet 231 no longer attracts the metal disc 224, and the suction cup assembly 22 switches from the locked state to the released state. During the switching process, the turntable 222 moves upward under the push of the first spring 225. During this process, the suction cup 221 adsorbs the surface of the infusion bag; the fourth drive motor 329 drives the positioning assembly 32 to rotate, and then the positioning assembly 32 can drive the infusion bag and the suction cup assembly 22 to rotate on the sorting bracket 21. When the sensor 213 detects the infusion port of the infusion bag, the fourth drive motor 329 stops rotating; the lifting assembly 31 drives the positioning assembly 32 to rise, so that the positioning assembly 32 is no longer in extrusion fit with the infusion bag. At this time, the push rod 315 no longer cooperates with the slider 245, and the magnet assembly 23 slides upward along the guide sleeve 214 under the push of the second spring 234. The magnet 231 attracts the metal disc 224, and the suction cup assembly 22 switches from the released state to the locked state. At this time, the infusion bag will not move and rotate during the conveying process.

[0058] The annular conveyor 12 moves the sorting mechanism 2 and the infusion bag to the corresponding infusion box 13; after the second drive motor 247 drives the lifting hook 248 to at least partially extend from the slider 245 through the gear and the tooth 249, when the first drive motor 246 drives the slider 245 to move along the rectangular groove 212 towards the infusion box 13 through the rack 241, the drive rod 242 and the connecting rod 244, the lifting hook 248 is inserted into the hanging hole of the infusion bag; when the drive rod 242 cooperates with the second push rod 236, the second push rod 236 is pushed downward, thereby driving the magnet assembly 23 to slide downward along the guide sleeve 214, and the suction cup assembly 22 is switched from the locked state to the released state; when the first drive motor 246 continues to drive the rack 241 and the drive rod 242 to slide towards the infusion box 13, when the slider 245 moves above the infusion box 13, the first guide rod 216 cooperates with the reversing groove 243 to drive the drive rod 242 to turn downward by 90 degrees. During the process of the drive rod 242 turning, the side of the infusion bag provided with the infusion port turns downward first, and then the hanging hole of the infusion bag slides out of the lifting hook 248, and the infusion bag falls into the infusion box 13. At this time, the side of the infusion bag provided with the infusion port is downward, and the side provided with the hanging hole is upward, and the label on the infusion bag is facing forward.
